Ultra micro-grain quality carbide tools series
High precision reamer

.High precision profile (compound) reamer series by solid ultra micro grain quality carbide(1-18 flutes, straight edge, oblique edge)
We can also produce SKH4C/ASP60 series according to drawings, samples, size tolerance.
.We used of advanced strong high speed CNC from Germany & Switzerland & high precision profile grinding (3DXTec)by ultra strong quality carbide. Have perfection quality of edge and size tolerance up to 0.001mm(1m) high.
 
.High precision products, surface roughnessR0.15m, concentricityѡ3m
.Grades
   .High impact resistance diamond tungsten steel(for intermittent cutting)VRA201/VRA221/VRA441
   .High hardness quality carbide (for super high wear resistance)HRF10/NRB10Z
 
   .Tungsten steel meeting ISO standard (for general machining)MR11/PR40
.For all kinds of high-hard material HRC50~64& non-ferrous metals , light alloy and high requirement wear-resistance reamer machining.
  Mid-low speed intermittent reaming machining for stainless steel, alloy steel, casting, application
